Deffense [45]

9514 1404 393

Answer:

continuous
distance traveled by walking

Step-by-step explanation:

You can draw the graph without lifting your pencil, so it is "continuous."

Time, on the other hand, is continuous--able to take on any value.

The graph best models distance as a function of time.
